Definitions
- This invention relates generally to fuel injection systems for internal combustion engines, and in particular to a fuel pressure regulator valve that integrally mounts on a fuel rail.
- Typical sealing means comprises one or more O-ring seals, which are usually made of a fuel-resistant elastomer.
- WO 90/03513 depicts a fuel pressure regulator which is representative of this design.
- the O-rings will remain on the valve when it is removed from the socket, but the design possesses a relatively expensive construction for the regulator valve housing and requires fuel pressure testing.
- the housing comprises three parts, namely a stamping and two screw machined parts which are assembled with the use of both brazing and crimping.
- the grooves that are required for the O-ring seals are in one of the screw machined parts and the brazed joint which joins the stamping and one of the screw machined parts and bounds the fuel chamber is outside the zone of sealing that is provided by the O-ring seals. Because of this construction, pressure testing of the brazed joint is essential to ensure that it does not leak.
- U.S. Patent No. 4,883,088 depicts a fuel pressure regulator which is similar to such a design.
- the present invention relates to a new and unique construction for a fuel pressure regulator valve mounted integrally on a fuel rail whereby the O-ring seals will remain on the valve when the valve is removed from the fuel rail while the O-ring retention on the valve housing does not require the use of screw-machined parts to provide the grooves for the O-ring seals. Moreover, brazing of a stamping to a screw-machined part is avoided, and fuel pressure testing of such a joint is likewise avoided.
- Fuel pressure regulator valve comprising a housing containing a movable diaphragm assembly that divides the housing into two chambers, one chamber being a fuel chamber that is cooperatively defined by said diaphragm assembly and a first portion of said housing, and the other chamber being a control chamber that is cooperatively defined by said diaphragm assembly and a second portion of said housing, a fuel inlet port via which fuel flows to said fuel chamber, a fuel outlet port via which fuel flows from said fuel chamber, a tube that forms a portion of a flow path extending from said fuel inlet port through said fuel chamber to said fuel outlet port and that has at one end thereof a valve seat disposed in said fuel chamber, and a valve element that is carried by said diaphragm assembly for coaction with said valve seat to perform a pressure regulating function on fuel occupying said fuel chamber by selectively restricting flow passing to said fuel outlet port from said fuel inlet port, characterized in that said first portion of said housing comprises a first stamped metal housing part and a second stamped metal housing part which
- Fig. 1 is a longitudinal cross section through a fuel pressure regulator valve mounted in a fuel rail socket.
- Fig. 2 is an enlarged view similar to Fig. 1, but presenting only a sub-assembly during a stage of the process for fabricating the fuel pressure regulator valve.
- Fig. 1 shows a fuel pressure regulator valve 10 mounted integrally on a fuel rail 12, the latter being only partially shown in the drawing.
- Fuel rail 12 comprises a stamped metal part 14 in which is formed a circular cylindrical socket 16 shaped to receive valve 10.
- Socket 16 comprises in succession from the top, a larger diameter side wall portion 18, a shoulder 20, and a smaller diameter side wall portion 22.
- Valve 10 comprises a housing 24 which has a circular cylindrical shape.
- Housing 24 comprises three stamped metal parts that are joined in assembly. In succession from the top in Fig. 1 these three parts are: an upper metal stamping 26, a middle metal stamping 28, and a lower metal stamping 30.
- a movable diaphragm assembly 32 divides housing 24 into a control chamber 34 and a fuel chamber 36.
- Control chamber 34 is cooperatively defined by part 28 and the diaphragm assembly; fuel chamber 36, by the diaphragm assembly and parts 28 and 30.
- the radially outer margin of the diaphragm assembly is captured by flange structure 31 that extends around the outside of housing 24 and that also serves to join parts 26 and 28 in assembly.
- This flange structure comprises the lower portion of part 26 and the upper portion of part 28 being shaped for sandwiching the diaphragm's outer margin while the terminus of the upper portion of part 28 is wrapped over and around the lower portion of part 26.
- This flange structure is conventional in the manufacture of certain fuel pressure regulator valves.
- part 24 is conventional in that its top wall comprises a central nipple 38 surrounded by a spring seat 40.
- a helical spring 42 is disposed in control chamber 34 between spring seat 40 and a central region of diaphragm assembly 32 to urge the diaphragm assembly away from chamber 34 and toward chamber 36.
- diaphragm assembly 32 Details of diaphragm assembly 32 are also conventional, and reference may be had to commonly assigned U.S. Patent 4,928,729 (Hornby) for a description. Suffice it to say for the moment that the diaphragm assembly centrally carries a swivelly-mounted valve element in the form of a truncated sphere 44.
- Stampings 28 and 30 cooperate with a tube 46 and an annular filter element 48 to form a sub-assembly which is shown by itself in Fig. 2 at one stage of the process of fabricating valve 10. This stage is before parts 26 and 28 are joined together to sandwich the outer margin of the diaphragm assembly.
- Part 30 is shaped to comprise a circular cylindrical sleeve 50 with a rolled flanged 52 at its lower end and a wide flange 54 at its upper end.
- Part 28 is shaped to comprise from the top in Fig. 2: an axial portion 56, a radial portion 58, an axial portion 60, a radial portion 62, and an axial portion 64.
- Filter element 48 fits over sleeve 50 and against flange 54.
- the entirety of axial portion 64 Prior to association of part 28 with part 30, the entirety of axial portion 64 is straight (broken line position of Fig. 2) and essentially parallel with axial portion 60.
- flange 54 This allows flange 54 to be telescopically disposed within part 28 with its radially outer margin against radial portion 62 during the step of joining parts 28 and 30 together. It also allows the radially outer margin of filter element 48 to be disposed within part 28.
- axial portion 64 is deformed from the broken line position to the solid line position in Fig. 2 whereby the portions 62 and 64 are formed into a crimp that engages the outer margins of filter element 48 and flange 54 and thus unites these three parts in a sub-assembly ready to be assembled with part 26 and diaphragm assembly 32 in the manner previously described.
- the material hardness of part 28 is chosen to allow for the proper formation of the crimp, and for example, steel having a Rockwell B scale hardness between 45 and 65 is quite suitable.
- Tube 46 and part 30 are in assembled relationship by virtue of sleeve 50 having a press-fit around the outside of the tube.
- tube 46 is a machined metal.
- a proper press-fit of the sleeve on the tube is attained by an appropriate material hardness of part 30, for example steel having a Rockwell B scale hardness of at least 85.
- Tube 46 is disposed such that its upper end 66 is juxtaposed to the truncated surface of sphere 44. End 66 is shaped to form a valve seat against which the truncated sphere surface can be disposed.
- the two part construction which consists of parts 28 and 30 is especially advantageous.
- One advantage is that it provides both suitable material hardness for the press-fit engagement of tube 46 with sleeve 50 and suitable material hardness for the crimp joint that holds the parts 28 and 30 in assembly, the latter hardness being less than the former.
- Another advantage is that the crimp also functions to define a portion of a radially outwardly open groove 68 for an O-ring seal 70.
- groove 68 is defined by radial and axial portions 58 and 60.
- an O-ring spacer 72 can be disposed to aid in locating the O-ring seal in the groove.
- the drawing shows the spacer disposed between the O-ring seal and radial portion 58.
- the spacer need not be circumferentially continuous, and for example a split ring of suitable plastic could be used.
- the O-ring spacer would be expanded to pass over the crimp and lodge in the groove.
- the selection of a suitable elastomeric material for the O-ring seal would enable it, even though it is circumferentially continuous, to be stretched sufficiently to pass over the crimp and then contract onto the tube within the groove.
- Flanges 52 and 54 cooperate with sleeve 50 in forming a further radially outwardly open groove 74.
- a further O-ring seal 76 and a further O-ring spacer 78 occupy groove 74 with spacer 78 being disposed between seal 76 and flange 54.
- the fuel inlet port for the valve comprises several through-holes 80 in flange 54.
- Filter element 48 is constructed to support a screen 82 in covering relation to these through-holes so that any particulate material in the fuel which reaches the screen and is larger than the screen's mesh will be prevented from entering the fuel chamber.
- the fuel outlet port for the valve is the open lower end of sleeve 50.
- Integrated mounting of valve 10 on fuel rail 12 is accomplished by aligning the main longitudinal axis of the valve with that of socket 16, passing the lower end of the valve through the open upper end of the socket, and increasingly inserting the valve into the socket until flange structure 31 abuts the fuel rail around the top of the socket.
- the two O-ring seals bound a space 84 that is cooperatively defined by respective portions of the valve housing and the socket.
- Through-holes 80 are in fluid communication with this space via screen 82.
- Pressurized fuel within the rail is communicated to space 84 via through-holes 86 in shoulder portion 20.
- pressurized fuel can pass from the rail to space 84 and thence to the valve's fuel chamber 36.
- the valve functions in a conventional fuel pressure regulating fashion.
- Spring 42 tends to force sphere 44 against seat 66 to close tube 46 to flow.
- a pressure in fuel chamber 36 that is sufficient to overcome the spring force, as modified by whatever engine manifold vacuum is communicated to control chamber 34 via nipple 38, will urge the diaphragm assembly upwardly and begin to unseat the valve element so that fuel can pass from chamber 36 through tube 46 and out the valve outlet port.
- the extent to which the valve opens is a function of the relative pressures in the two chambers and the spring force. The valve opening is such that the flow restriction which it presents will cause the upstream pressure to be regulated.
- valve outlet port passes through the open lower end of socket 16 to a fuel return.
- the fuel rail is constructed such that the pressurized fuel zone of the rail is sealed from the return flow.
- the integrally mounted valve is mechanically captured in the socket by a retainer, which is not shown in the drawing. Should it ever become necessary to remove the valve from the socket, the retainer is first removed, and then the valve can be removed. When the valve is removed, the O-rings remain on the valve.
